Material examined.

G. atripalpulus : CHINA • 1 ♀ 1 ♂ (4547, 4548); Hubei Prov., Shiyan City , Danjiangkou County, Wudangshan (111 ° 04 ′ E, 32 ° 28 ′ N); 19 Jun. 2021; Wen-Xuan Bi leg. ( ECNU) . — G. atripalpulus (= G. cirilinearis ): CHINA • 1 ♀ 1 ♂ (4535, 4536); Shaanxi Prov., Ankang City , Langao County, Dabashan (108 ° 54 ′ E, 32 ° 18 ′ N); 13 Jun. 2021; Wen-Xuan Bi leg. ( ECNU) . CHINA • ♀ (4539); Shaanxi Prov., Ankang City , Langao County, Dabashan (108 ° 54 ′ E, 32 ° 18 ′ N); 15 Jun. 2021; Wen-Xuan Bi leg. ( ECNU) .

Diagnosis.

Apterous; mesonotum and metanotum pubescent slightly, abdomen pubescent slightly in females, but only the first three segments of abdomen pubescent slightly in males (Fig. 3 D, E ); yellow stripes extending from occiput, along eyes to lateral ocelli, the yellow stripes divided into two branches from the middle of eyes (Fig. 4 I, J ); maxillary palpus black (Fig. 5 H, I ); male genitalia: apical part of epiphallus with two divided lobes, the inside of lobes without process (Fig. 6 E, F ); abdomen: female with four yellow-brown spots on the 2 to 8 segments, but black in males (Fig. 3 D, E ).

Remarks.

The main difference between G. cirilinearis and G. atripalpulus is: the occiput of G. cirilinearis is ornamented by two short reddish-brown stripes, while that of G. atripalpulus is not ( Xie 2005). However, the molecular result indicates that they are the same species. They all possess the above morphological features in diagnosis. Besides, the length and width of stripes on occiput are varied in our study (Fig. 3 D, E ). Thus, we regard the short reddish-brown stripes as infraspecific variations in this species. Therefore, we place G. cirilinearis syn. nov. in a junior synonym of G. atripalpulus .

Measurements.

(mm) ♂: BL 13.84–14.89; PL 2.79–3.71; HFL 7.93–9.04. — ♀: BL 14.11–15.66; PL 3.14–3.71; HFL 9.37–9.75; OL 11.34–11.79.

Distribution.

China (Gansu, Hubei, Shaanxi).
